VALVE.

Originol application filed December 31, 1920, Serial No. 434,179.Divided and this Vapplimzitioii led August 13, 1921.

nois, have invented certain new and useful Improvements in Valves, ofwhich the following is a specification.

My invention relates to a multiple port valve device or circulationcontroller of the rotary type for governing the circulationof fluidthrough a pipe system; this application being a division of my(so-pending applica-V tion Serial No. 434.179, tiled December 31, 1920,for automatic car heating systems, 'in which the valve device isemployed to autoinatically control the inflow of steam to and thedischarge of medium, including water of condensation,` from theradiating coil of the car heating apparatus.

A principal ob'ect of the invent-ion is to provide a new an improvedvalve device, or 'circulation' controller of this character suitable foruse in the above mentioned or analogous situations. A particular objectis to so construct the device that 'water of condensation may bedischarged therethrough from an intermediate pointiin the radiatingcoil-` as well as from the discharge end ofthe coil,

whilethe Vdevice is set for admitting steam t such coil.

A further object of the invention is to pro-fvide a novel and improvedelectrically actuated mechanism for shifting the valve from one positionto the other.

A further object isto provide for hand operation of the valve in casethe electric apparatus is accidentally or intentionally disabled.

A further object is to provide an actuating means for the valve whichwill be compact, positive and reliable in its action. simple inconstruction and economical to manufacture and install.

The invention consists in the new and improved arrangements,construction and devices to be hereinafter described and claimed forcarrying out the above stated objects and such other incidental objectsas will be mentioned in the description that follows of the preferredembodiment of the invention shown in the accompanying drawings.v

Referring first to Figs. 5 and 6, A is the steam train pipe of a railwaycar, the radiating coil of which is Shown as consistingof two sections Band C. D is the circulation controller of the radiator, E and F the motors o erating the same. G the v apoi` regulator, the limit switch forswitching the current alternately to motors E and F, and Q the batteryfor supplyingelectric current.

The circulation controller or valve device is preferably constructed ass hown in Figs. 1, 2, 3 and 4. 25 is a casing divided by interior websinto a centralcircular space 26, in which is arranged Zap-rotary valve27, and around said circular space into a plurality of chambers whichfor convenient reference will be given the following somewhat arbitrarydesignations and are numbered on the drawings as follows: 28 is a supplychamber connected by pipe 34 with the train line 29 is a dischargechamber connected by pipe 39 with the thermostat chamber of the vaporregulator G; 31 is an inlet chamber from which leads the inlet pipe 35of radiator section B; 32 is a first return chamber to which extends adrain pipe 36 from the return end of radiator section B; 30 is a secondreturn chamber to which leads the return end 38 of radiator section C;and 33 is a drip chamber having a port communicating with a drip pipe41. t

The first return chamber 32 lis connected with the discharge chamber 29by a duct 40 formed in the casing under the above mentioned chambers.This duct might extend to the second return chamber 30 instead of todischarge chamber 29 since, as Willappear, chambers 29 and 30communicate with each other at such times as the duct 4() is necessaryfor the proper operation of the controller. This duct is arranged so asto be water sealed against the escape of steam. .c

The valve 27 comprises a lower disc 421, an

v by rivets 66.

upper 43V and Webs 44, 45 and 46, the upper disc being' formed with astem 47 eX- tending through a bonnet 48 on the top of casing 25 andthrough a packing 50 and packing' gland 5'1. thereto a lever 52terminating, preferably in a handle 53. 54 isa pivot stud on the lowerdisc42 which lits a recess 55 in the bottom of the casing. The lever 52is formed with a widened portion 56 having c'ur'ved edges and thisportion of the lever is engaged b y a pair of heads 5l formed on theunitar structure 58 forming the cores of the soleno1d motors E and F`The opposite end 59 of lever 53 'is provided with a depending stud 60*engaging a collar 61 on the switch member G2 of limit switch H. Thisswitch member is composed of insulating material and slides in' suitableopenings in bloeit 63. A pair of spring contacts 64, 64* secured to oneof the blocks 63 Vare adapted tov bear against the contact plates 65, 65on member 62,A these plates being' electrically connected Secured tothe' other block 63 is a similar pair of Contact springs 67` 67*xadapted to engage the contact plates 68 on the corresponding' end ofmember 62. The arrangement is such that when the contact springs 67, 67*bear against the plates 68, 68,-

fhe contact platesV 65 are o'ut of touch with s'p'ring's '64, 64, andvice versa. 69 is a; hod on the top of casing' 25 enclosing the innerends of4 the solenoids and the limit switch.

The vapor regulator G is a device in common use for maintaining thesteam in the radiator at substantially atmospheric pressure. For detailsof construction reference is' made to the patent to Gold, 1,077,525,Nov. 4, 1913. In the present connection it will be sufficient to statethat the device comp'ri'seg a pressure reducing valve 70 arranged ina'valve casing 71 which is interposed in the slu'p'plj-v pipe 34. Valve 70is operated by a bell c i'anl 72 to which is attached a stem 73 hearing'upon a flexible capsule 74 filled with a liquid which expands underheat. This capsule or thermostat is arranged in a thermostat chamber 75to which discharge pipe 39 lea'ds. Uutflow of live steam throhf'g'h pipe39 expands thermostat 74, throttling down valve 7() to limit inflow tothe radiator.

Operation:A Fig. 5 shows the position of the parts ot the apparatus atsuch time as the radiating coil is receiving steam from drain 'pipe A.Stem lloirs through pipe 34 past lvalve o f the vapor' regulator whichautonlaticallv governs the volume of steam introduced ihto the radiatorin accordance with the ilr'nou'nt required to keep the same filled(assuming valve D is in the open position) t atmospheric pressure. Frompipe 34 steam passes through chambers 2 8, 31, pipe, 35 o coil B,through radiator section B into pipe 37 'of radiator section G andthrough The stem 47 has fixed) radiator section C. The Water ofcondensation outflows from radiator section B through pipe 36, firstreturn chamber 32, duct 40` discharge chamber 29 and pipe 39 to thethermostat chamber of the vapor regulator G. Duct 40 is sealed againstthe escape this way of steam. Water of condensation (and steam incertain quantities when the system is working at capacity) outflows fromradiator section C throu h pipe 38, second return chamberA 30,disciiarge chamber 29 and pipe 39. When the' car temperature has reacheda-certain point valve member 27 is rotated by motor F through theoperation of certain thermostatically actuated control ling deviceswhich are shown in my co-pending application Serial No. 434,179 abovereferred to but which form no part of the present invention. Tliesedevices serve, when actuated', to close a circuit throuo'h motor F asfollows; Battery Q. wire ljg, winding of solenoidy F, wire- 140, contactspring 67, contact plate 68', Contact spring 67. wire 141 to thebattery; the thermostatically actuated controlling devices beingconnected with the wire 141 at the' place1 for example, indicated bythe'broken lines. So far as the present invention `is concerned, ang,rsuitable means might be employed for closing the circuit at this place.

The valve 27 and limit Switch H are now moved to the ostion shown inFig. 6,. Web 44 shuts off t c su ply chamber 28 from all of the otherchambers except the discharge chamber 29. Webs' 45 and 46 are moved sothat the other chambers are all in communication 'with the dripchamber33. Steam now flows from pipe' 34 directly to pipe 39, and, by operationof the pressure l'reducing valve 70 of the vapor regulator just enough,steam follows this course to keep the vapor iregulator Wai-m as againstfreezing, without wastag'e. Wter of condensation from IUI.)

the inlet pipe 35 and from the' return pipes I 36, 38 outflows throughthe drip pipe 41. Duct 40 is water 'sealed so that with the low pressureof steam handled there is no backing up of steam from the dischargechamber 29 into the radiator.

When the thermostatic controlling devices (or equivalent circuitcontrolling means) operate to again close the break in conductor 141,which in the arrangement shown will be o'n fall of the car temperatureto a certain point, motor E is energized to return thc valve to theposition of Fig. 5 by the closing of a circuit as follows: Battery Q,wire 139, wire 145, winding' of solenoid E, wire 146, spring contact 64,contact plates 65,

spring Contact 64, wire 147. wire 141, to battery.

The limit switch, it will oe observed, is moved by the 'valve itself soas to alternately direct the current to the mot/or operating sle'noid's'E and F.

The valve 27 has been referred to as being in the open position whenturned to admit steam to the radiator and direct outiiowing medium tothe thermostat chamber of the vapor regulator as shown in Fig. 5. Byrer'erring to the valve as in the closed position (these terms beingnecessarily somewhat arbitrary in a valve-ierice of this sort) I intendthe position of the ralvc'as shown in Fig. 6 in which the steam is shortcircuited to the vapor regulator. These terms may have'to be construedin a relative rather than in an absolute sense in case, as is within thescope of the present invention, the controller is put to a use differentfrom that hereinabove described.
